1. To make the burgers: add the doritos to a food processor, blender or into a bag and crush with a mallet. Blend into a fine crumb texture. In a large shallow bowl, combine crushed doritos, ground beef, garlic powder, oregano and season with a good amount of salt and pepper. Use your hands to mix well. Form 6-8 oversized balls (3-4 oz) for the burgers and set aside. Or form 2 oz regular sized burgers (about 12).
2. To make the sweet and spicy sauce: in a bowl mix together the mayonnaise, mustard, honey, chili flakes, jalapenos (add more for extra spicy). Mix until well combined. For a subtle beer flavour add just a touch to the sauce to make it a little thinner.
3. For the onion rings(if using frozen, bake according to package directions): Cut the onion into 1/2 inch thick rounds. Separate each layer into individual rounds. In a shallow bowl, combine flour, cornstarch, baking powder, baking soda, paprika and salt. Mix to combine with a fork. Coat each onion ring into the dry mixture and set aside. Once all the onion rings are done, seperate the mixture in half into another shallow bowl. To that bowl pour in 1/3 cup of beer. The mixture should resemble a pancake batter. Dip each ring into the beer battered and again into the remaining dry mixture. Repeat until all are done.
4. Heat vegetable oil to 350 degrees F. Once the oil is hot, drop in the onion rings and cook for roughly 1 minute per side. Do this in batches if needed.
5. When ready to cook the burgers, press them down directly on the grill using a large metal spatula. If you don't have one, you can pre-press them using the back of a side plate. Press the burger down until it reaches the size of the buns. The patties should still be thick. Cook flipping once about 3-4 minutes per side. Melt the cheese directly on the burgers during the last minute of cooking.
6. To serve: spread the sauce on the bottom and top buns, add the dorito patties and top with a few crispy onion rings. Enjoy!
